Intonation: Theory, Models, and Applications
Segmental factors can cause large temporal changes in local pitch contours associated with accented syllables ("accent curves"), but these changes are often not phonologically or perceptually significant. Yet, other factors can cause temporal changes that are smaller but nevertheless significant. We propose a model according to which accent curves are (phonologically, perceptually) equivalent when they are generated from the same accent curve template using a shared family of time warp functions. The model is shown to provide a detailed and accurate account of alignment of accent curves over a wide range of segmental configurations.
